Good game! Some of the things I noticed were the game resenting rather than restarting the room when the player died, which is frustrating. Also its a bit difficult to know what enemies are doing what. It would be nice if they would show an arrow based on where they want to go if they are of the more predictable nature, and the more random ones can keep their anonymity.
Also, Movement should have a sound effect., and the sprite should switch its up and down on versions based on when the player moves rather than after a set delay.
